Used BOSS SD1 Super Overdrive Effect Pedal

In great condition, this used BOSS SD-1 Super Overdrive delivers the classic warm, mid-focused drive that’s perfect for pushing a tube amp or adding smooth grit to clean tones. Simple, reliable controls—Level, Tone, and Drive—make it easy to dial in everything from subtle boost to singing overdrive. Built like a tank with BOSS’s rugged compact design, it runs on a 9V battery or standard 9V DC adapter and features 1/4" input/output for easy pedalboard integration.
